I KNOW that Howard Morris had a guest appearence on "Head of the Class," in an episode where Billy brings the class upstate, and they meet some stereotypical rural characters. The only trouble is IMDb doesn't cover it, but they will as soon as I get some info. What was the name of the episode?

The name of that episode is "Fillmore vs. Billy Jeans". What character did he play?
